Week in Core, Apr 19– Apr 26 2016

Welcome back the latest issue of Week in Core, covering changes [37254-37314]. Here are the highlights:

Ticket numbers based on trac timeline for the period above.

Code Changes

Build/Test Tools

  • Build/Test Tools: Reset the PHPMailer mock in Tests_Mail::tearDown(). [37307] #36609
  • Tests: Use the same incrementor for all fields belonging to a given text fixture. [37299] #35199
  • Don’t announce PR builds in Slack. People may submit a PR to our travis build repo, we shouldn’t notify slack when that happens. [37268] #36607
  • Tests: Allow override of MULTISITE and SUBDOMAIN_INSTALL constants [37266] #36567

Canonical

  • Use get_the_terms() to verify that a post belongs to the requested %category%. The get_the_terms() wrapper provides cache support, and saves a database hit
    on sites with a persistent cache backend. [37262] #36602
  • Tests: After [37260], use WP’s setUpBeforeClass() wrappers. This ensures no leakage between tests of fixture IDs. [37261] #36602
  • Add tests for permastruct containing /%category%/. [37260] #36602

Comments

  •  Add a $comment parameter to get_comment_author_url_link(). Add unit tests (none exist). [37305] #36573
  • Add unordered list styling to Comments List Table rows and Moderate Comment screen. [37304] #36160
  • Keep comments safe in the Edit Post screen. Warns users that have added a new Comment or began editing an existing without saving their changes, before they press the “update” button which would wipe out their comment changes. [37303] #32818
  • Dashboard: toggle the “View” link for comments when Approving / Unapproving from the Dashboard widget. [37302] #35518

Database

  • Suppress connection error messages when WP_DEBUG isn’t enabled. This is a partial revert of [35860], which has been causing un-catchable warnings to be generated on some server configurations. [37293] [37292] #36629, #21870

Date/Time

  • Tests: Pre-declare the $year_url property before initialization in Tests_Get_Archives::setUp(). [37271] #36611

Docs

  • Add missing return descriptions for WP_Filesystem_SSH2::chown() and WP_Filesystem_SSH2::run_command(). [37270] #30989
  • Clarify the return descriptions for get_the_time(), get_post_time(), and get_post_modified_time() to specify when an integer in the form of a Unix timestamp should be expected. [37265] #30989
  • Clarify return descriptions in the DocBlocks for set_user_setting() and delete_user_setting(). [37264] #30989
  • Clarify parameter and return descriptions in the DocBlock for wp_set_all_user_settings(). [37263] #30989
  • Capitalize URL – an acronym for Uniform Resource Locator – when used in the context of inline docs in wp-includes/link-template.php. [37259] #30406
  • Notate more optional parameter defaults for a variety of function DocBlocks in wp-includes/link-template.php. [37258] #30406
  • Notate optional parameter defaults for a variety of function DocBlocks in wp-includes/link-template.php. [37254] #30406

Editor

  • TinyMCE: prevent showing the placeholder URL when adding a link and clicking more than once on the Insert Link button. [37301] #36637

Emoji

  • Smilies: Move convert_smilies to happen later in the the_content filter. [37298] #36306
  • The :roll: smiley is now an emoji. [37296] #36365
  • The diversity support test was incorrectly passing on all browsers. [37257] [37256] #36604

Feeds

  • Revert [36230] which removed the rss-http feed content type. Removing this means that any feeds which are using this feed content type are now being served as application/octet-stream instead of text/xml. [37284] [37282] #36620

General

  • Customize/Formatting: Move sanitize_hex_color(), sanitize_hex_color_no_hash(), and maybe_hash_hex_color() from class-wp-customize-manager.php into formatting.php. Adds missing braces. [37283] #33413, #27583
  • Administration: Introduce admin_print_footer_scripts-$hook_suffix", a dynamic version of the admin_print_footer_scripts hook. This is now more consistent with the generic admin_print_scripts and the dynamic admin_print_scripts-$hook_suffix hooks fired in wp-admin/admin-header.php. [37279] #34334

Media

Networks and Sites

  • Tests: Account for flexible IDs in main network deletion test. [37300] #36566
  • Tests: Exclude ms-files test group from default PHPUnit config. [37269] #36566
  • Tests: Add speedTrapListener to multisite’s PHPUnit config [37267] #36566, #30017

Posts, Post Types

  • Add parameter documentation for ‘post_category’ to wp_insert_post(). [37255] #36601

Post Thumbnails

  • Fix logic bug and tests from [37308] where post-thumbnails support wasn’t added if there were no previous post_types with support already. [37313] #22080
  • When using add_theme_support( ‘post-thumbnails’, array( $post_types) ) merge the supported post_types. [37308] #22080

Query

  • Tests: More explicit fixture content when testing s=0 query string. After [36647], the unit test generator sequence can put a 0 into the
    ‘post_excerpt’ field of a post fixture, causing false positives. [37280] #36622

Rewrite Rules

Taxonomy

  • Docs: Move the clarification of is_tax() and WP_Query::is_tax() return value added in [37235] to @return description. [37281] #36331

Text Changes

Themes

Upgrade/Install

  • Clear plugin/theme caches directly after a plugin/theme has been updated. This is a follow-up to [34751]. [37272] #34029, #36383

Users

  • Remove the “Name” column of the Users table from appearing sortable. [37314] #28064
  • Docs: Reflect the new 'user' option for wp_new_user_notification()‘s $notify parameter added in [37276] in wp_send_new_user_notifications() docs as well. [37278] #36009
  • Add a unit test for [37276]. [37277] #36009
  • In wp_new_user_notification(), sdd 'user' option for the $notify parameter, which allows for sending notification only to the user created. [37276] #36009
